Abstract
The utility model relates to a wind power generating device, which comprises a tower base, a generator, an accelerating gear box, a transmission axle and a blade. The utility model is characterized in that the transmission axle is vertically arranged on the center of the tower base and the blade is in a fusiform shape. A wind facing surface is a concave surface and a back surface is a convex surface. The small end of the blade is arranged on the upper end of the transmission axle and the inner part of the horizontal circumference of the same height on the upper end of the transmission axle is provided with at least three blades with equal intervals. The utility model has the advantages that the utility model is not limited by a wind direction, the wind of any wind direction can form dynamic force, the tower base is not required to be highly built, the cost is low and the installation and the maintenance are easy. The utility model is not only suitable for building large wind generator sets but also is suitable for building middle and small wind generator sets in the use of wide mountain areas and remote areas to solve the problem that the electricity use of the wide mountain areas and the remote areas is difficult.
Description
Technical field
The utility model relates to a kind of wind generating unit.
Background technique
Wind-power electricity generation belongs to renewable energy sources, by implementing the wind-power electricity generation of one of renewable energy sources and new energy hi-tech industrialization, can promote the mixing together of renewable energy sources and new energy industry and related industry, promote renewable energy sources and new energy industry spur development model to market from government's leading type transformation, cultivation has the enterprise and the enterprise group of the strong market competitiveness, establishes the inherent mechanism that is beneficial to China's renewable energy sources and the long term growth of new energy industry.At present, the wind generating technology comparative maturity, be widely used, market prospects are wide and can have induced effect to regional economic development.Existing wind generating unit kind is a lot, but all comprise the tower tube basically, generator, step-up gear, transmission shaft, blade, generator, step-up gear is installed in the top of tower tube, blade is installed in the transmission shaft front end by air guide sleeve and wheel hub, transmission shaft is connected with step-up gear, the transmission shaft of this type of electricity generating device is parallel with horizontal plane, the surface of revolution of blade is vertical with horizontal plane, enough height that this just requires the tower tube to build, the material of blade and transmission shaft is good, the intensity height, and this type of electricity generating device must be installed weathercock instrument and yaw system, thereby caused electricity generating device automatical control system complexity, single unit system cost height, difficulty is installed, difficult in maintenance, cause the cost of electricity-generating height, the scope of promoting the use of is restricted.
Summary of the invention
The purpose of this utility model is in order to overcome too high, the complex structure of tower tube in the prior art, to cause the high defective of cost of electricity-generating, the wind generating unit that a kind of whole height is low, simple in structure, cost is low, practical being provided.
The purpose of this utility model is realized by following mode:
The utility model comprises tower seat, generator, step-up gear, transmission shaft, blade, it is characterized in that: transmission shaft is vertically mounted on tower seat center, blade is a spindle, its wind-receiving face is a concave surface, the back side is convex surface, the small end of blade is installed in the upper end of transmission shaft, in the horizontal circumference of transmission shaft upper end sustained height at least three blades is installed equally spaced.
The utility model has the advantages that: not wind-engaging to restriction, arbitrarily the wind of wind direction all can form power, so to the utilization ratio height of wind, and weathercock instrument and yaw system need not be installed; It is very high that the tower seat need not be built, so cost is low; Transmission shaft of the present utility model is upright the installation, so generator can be installed in ground, is easy to install, safeguard.
Description of drawings
Fig. 1 is a schematic appearance of the present utility model; Fig. 2 is a structural representation of the present utility model; Fig. 3 is a plan view of the present utility model.
Embodiment
With reference to accompanying drawing, the utility model comprises tower seat 5, generator 7, step-up gear 6, transmission shaft 2, blade 1, transmission shaft 2 is vertically mounted on the center of tower seat 5, blade 1 is a spindle, its wind-receiving face is a concave surface, the back side is convex surface, the small end of blade is installed in the upper end of transmission shaft 2, the radially medial axis of blade 1 is vertical with transmission shaft 2, three blades equally spaced are installed in the horizontal circumference of transmission shaft 2 upper end sustained heights, generator 7, step-up gear 6 are located in the tower seat 5, and generator 7 is connected with transmission shaft 2 by step-up gear 6.In order to make the utility model also can normal power generation under the less situation of wind-force, one cover magnetic suspension force aid system can be installed between transmission shaft 2 and tower seat 5, concrete mounting type is the top that the automatically controlled magnetic means 4 of magnetic suspension force aid system is installed in tower seat 5, transmission shaft 2 passes from automatically controlled magnetic means 4 centers, and the center and the transmission shaft 2 of magnetic suspension disk 3 is fixing.Working method of the present utility model is: when wind moving vane 1 is made horizontal circular movement, drive transmission shaft 2 and rotate, thereby drive generators 7 generatings by step-up gear 6.
The utility model is not only applicable to build Large-scale Wind Turbines, more is applicable to build the medium and small wind power generating set that is fit to vast mountain area and remote districts use, to solve the problem of vast mountain area and power shortage from far-off regions.
